- Avoid the use of plug-ins.
- Information must also be provided in HTML format.
Where plug-ins are used to offer a feature rich experience:
- links to the application/experience must be explicit about what plug-ins (and versions) are required
- there must be clear links to alternative means of accessing the information or service
- Where a plug-in is required a link to download it must be provided by using our standard plug-ins page.
A plug-in is an extra program which can be installed alongside a user's web browser. A plug-in application is recognised by the browser and is used to display information in a particular way. Plug-ins require the user to download and install specialist software, or to install it from a CD. To some users this is impractical, to others impossible and to others undesirable.
Core information must not be provided solely as a plug-in. All information contained in sections requiring plug-ins must also be available in HTML. For example if speech is provided using RealAudio then a transcript must be provided in standard HTML. Where plug-ins are needed, the more commonly used technologies must be used.
Plug-ins standard list
- Flash (Flash animation is not permitted for 'decoration' purposes and can only be used if adding value to information.)
- Adobe Acrobat Reader (PDF)
Some advanced functionality or 'feature rich experience' can only be offered by using plug-ins. Where this is the case, it must be obvious to the visitor that by following the link a particular plug-in (and version) is required. A clear alternative to obtaining any information or service offered through the use of a plug-in must also be made clearly available at the same time.
Where a plug-in is required a hyperlink to download it must be provided by using the corporate standard plug-ins page.
